Very nice compilatiion. Deleting the commercials is a great convenience-the old commercials are of historical value and interesting, but not when you have to listen to the same one 40 times and they take up 5 minutes out of every 15 minute episode.
But the last 15 episodes of the story line are missing from this compilation. The remaining episodes are available at http://archive.org/details/Superman_page12
; Episodes 1566 through 1581 (a few of the episodes are missing from this group also, but Superman always gives you a good recap, and the resolution of the story is complete).
